About Trillium Architects

Trillium Architects is a 12 person, full service, boutique architectural firm specializing in Passive House, Net-Zero and off-the-grid new homes, additions, and renovations. Based in Ridgefield, CT, we primarily work in western Connecticut and New York's Hudson Valley, but we've designed homes all over the country.

In 2015 and 2016 we won awards for Best Energy Efficient Home in the USA from both the USGBC and the DOE, we won a 3rd Place International Innovation award which we accepted at the United Nations Framework Convention on Climate Change in Morocco 2016, and we won Best Emerging Firm in CT from the AIA in 2016.

With the end goal of marrying beauty, usability, and the cutting edge of efficient design, we strive to always make the client experience of building or renovating their home top notch.
